Octave
ETI Fuzz Struzz (a.k.a. Guitar Effects Unit)
There was a mistake on the layout, that’s now fixed. This calls for both +9V and -9V supply. Use of inverter pump daughter board is recommended. The GEU is good sounding octave fuzz, with an optional mode of just fuzz. The fuzz is a fully rectified signal and is quite chewy. For some the Fuzz … Read more
Octave Up Sick Box
Gus Smalley’s “Octave Up Sick Box”. And demonstative video from one cool dude who’s been around the blog sometimes too. He also has a few words of wisdom to share! Check it out! Built it using 1N60Ps for D1&D2, 1N4148s for D3-D6. Works like a charm. Well. A sick charm, but still 🙂 And here’s … Read more
John Hollis Frobnicator
This one is definitely verified, but: The LFO section is *very* sensitive to both voltage and current, so if your board doesn’t fire up right away (which happened with my second build too), you should consider doing a little daughterboard with 9V regulator, 8V2 zener and a 10-50 trimmer to get the LFO going. That … Read more
Escobedo Tripple Fuzz
When i started to draw layouts, i did draw something like 10 of vintage fuzzes that weren’t published on this blog earlier. I build most of them and that’s when i realized why they weren’t posted. Most of them are pure crap. For those who are after “that 60’s sound” – the ear piercing super … Read more
Mid-Fi Electronics Peace Gun Fuzz
Yay, our 100th fuzz pedal layout! And yes Vince, I know you’re going to be annoyed about one of the pots! :o) I left the power supply filter / smoothing cap optional because we know from previous experience that they can change the character of the fuzz and tame things down a bit, so I’d … Read more
Runoffgroove Buzz Box
Request. Info about the circuit from ROG: Another application of the Bazz Fuss design is the Buzz Box, also designed by Christian. The circuit is simply two BF in series, but the second BF stage uses a germanium diode rather than the usual silicon. The circuit produces a nasty (in a good way), explosive octave-up … Read more
Catalinbread Heliotrope
Info from Catalinbread about the original: What do you call an effect that isn’t quite a Bit Crusher, or an Octave, or a Harmonizer, or a Ring Modulator, or a Lo-Fi dirt box/fuzz – but a bit of a blend of each? Yeah – we don’t know either, so we came up with “Harmonic Pixelator”. … Read more
Fender Blender
This layout was based on the original schematic, but here’s the manufacturers info about the reissue: There are few Fender products with as much “indie cred” as the Fender Blender. Once thought of as an overly harsh fuzz pedal, the Blender, thanks to players like Billy Corgan of Smashing Pumpkins and Kevin Shields of My … Read more
Foxx Tone Machine
So I may as well include this one too. Manufacturers info: Manufactured for only a few short years in the early ’70s, the fOXX Tone Machine was stomped mightily by artists ranging from ZZ Top to Adrian Belew, Parliament-Funkadelic to Peter Frampton. Its legacy has lived on as a new generation of artists (Nine Inch … Read more
